Alstroemeria variety `Stalbel`

ABSTRACT

A new variety of Alstroemeria characterized by its very large blooms, the outer petals of which are distinguished by a mainly white coloration and having short, parallel streaks of a purplish color at each side of a short groove at the petal tip, the inner petals being more narrow in form and being mainly of a yellow coloration with the petal tips being white at their outer ends with a purplish blotch at the tip, the inner petals being further marked with short, deep purplish pencil stripes which spread outwardly from the base of the petals to the petal tips. This plant is further distinguished by its strong, vigorous and upright growth habit with the main stem reaching a height of about 180 cm., each stem bearing a raceme of many flowers at its upper portion and the flowers being produced profusely and continuously from spring through fall.

BACKGROUND OF THE NEW PLANT

This new Alstroemeria plant originated as a seedling resulting from my crossing of plants selected from individually identified members of my breeding stock maintained at Aalsmeer, The Netherlands, for breeding purposes, this particular seedling having been selected by me for propagation and test because of the very large size of its generally white flowers which appeared to be produced profusely on strong, upright stems from a generally umbel formation. This new plant has resulted from breeding efforts carried on by me at Aalsmeer since 1982 with the object of producing new types of Alstroemeria hybrids having new and unusual coloration. This particular seedling was selected by me for propagation and test beause of the very large size and generally white coloration of its blooms, the propagation being done by means of rhizomes with very satisfactory results which prompted me to direct further propagation of this new plant by dividing rhizomes of several successive generations, which demonstrated that the novel and distinctive characteristics of this new variety would hold true from generation to generation and appeared to be firmly fixed for continued asexual propagation.

DESCRIPTION OF THE DRAWING

This new Alstroemeria hybrid is illustrated by the accompanying photographic drawing which, in full color, shows flowers of a blooming umbel of the plant and demonstrates the unique and distinctive coloration and form of the flowers, the color rendition being as nearly true as is possible to obtain by conventional photographic procedures.
